I hate to play the opposing guy, but considering the source material two people could easily arrive at statues that similar by complete chance. I'm not saying they did or did not copy the former, but hunched over angry looked Hulk with one leg in front of the other is far from a trademark.
I've been scouting Syco's Facebook page and honestly they seem like a nice company. Their sculpts and paint jobs could be a little better, but they look to be improving with each release. Pretty much every single question, picture, or comment made on their wall they reply to and answer very quickly, giving specific information like saying if a statue is being touched up or what not. Regardless of the quality of the pieces or whatever controversy they have surrounding thing, I've got to respect a figure company that is quick and informative with responding the fans. It's pretty frustrating dealing with companies like Sideshow and Hot Toys sometimes, of whom seem so distant from the fans. We're just left sitting in these threads always speculating stuff, rarely getting answers.
